Different behaviour between Building/Testing and Deployed version

Hi over there,
I'm building a workflow to create some data in the pipedrive API.
Having the Postman API Requests running, i copied over the body of the requests and it works with the sample plain data. Even if i use the variables of the blocks, for example "startTrigger", they work on the workflow UI in testing mode (pressing play button on top right corner)

However, if i use the variables from for example "startTrigger" and deploy, it behaves different.

I have attached a screenshot of an example. The createDeal block works and creates the deal in Pipedrive as expected using the UI, pressing play.

If executed as deployed version, see what appears in pipedrive.
